Beräkning av energianvändning i svenska småhus

An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.

Majs till mogen skörd :

Corn is an important food and feed crop in the world, in Sweden it?s up till now grown on limited acreages mainly for silage. But I think it can get more important if you can grow it also for grain, because it?s a good animal feed for example, for life stock-, pigsand poultry. On of corns advantage is that it can produce the same amount of dry matter as for example wheat, barley and rise but with 25% less water. I will examine if it possible to grow corn for grain production in the south of Sweden.

Designated Operational Entities. En legitim form av offentlig-privat governance inom ramarna för Clean Development Mechanism?

This thesis investigates the Designated Operational Entities (DOEs) under the Clean Development Mechanism (CDM) of the Kyoto Protocol. The DOEs serves as independent third-party auditors with the task of validating, verifying and certifying projects under the CDM. The majority of the DOEs are private entities. This is in line with the CDM objective of including the private sector in the climate change combat. The introduction of private entities in the role of DOEs can be questioned from a legitimacy point of view, but is corresponding to a development in international environmental governance where private actors are increasingly involved in governance arrangements.The thesis concludes the DOEs to be a form of public-private partnership and investigates the legitimacy of this form.

Vindkraft eller kärnkraft - En jämförelse

The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

Primärenergianvändning av passivhus i Sverige : Med fokus på Kvarteret Trettondagen

The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.

Design och förädling av en liten och kustnära trädgård :

2. SUMMARY A small garden exposed to a harsh coastal climate can be difficult to design. Limitations in space and in plant varieties increase the needs of an in-depth knowledge to achieve wanted goals. In this degree project the challenge has been to create a functional and position adapted garden for a very small beach house lot in Mölle, a little harbour village at the south coast of Kullaberg. ?Villa Malm?, is situated directly on the bedrock in a close settlement where the gardens, in most cases are very small and exposed to strong salty winds.

Hot, våld och trakasserier : En studie om handlingsutrymme, politiska ledare och demokrati

Studies have shown that politicians are significantly more likely to become victims of violent crime than other citizens in Sweden. In fact increasing political rank and engagement are directly proportionate to increased risk for violence. Threat towards politicians is not only dangerous to the individuals involved but also to the democratic system as a whole.Political scientists the world over have done a lot of research on democracy, but I have been unable to find a single method or theory that examines how violence, threat and harassment affect political leaders and democratic systems.The aim of this study is to expand the existing model made by Tommy Möller, professor in political science. In his model he presents 11 factors that affect political leaders ability to act. My aim is to develop his model by adding a 12 th factor ?violence, threat and harassment?.

Skuggföredragande växter i trädgård

Detta examensarbete innehåller en beskrivning av växter som under olika förhållanden trivs och kan växa i områden med delvis eller hel skugga. Beskrivningarna av växterna är översiktliga och ämnar inte informera läsaren grundligt om växten utan enbart om enklare fakta för att kunna planera sin trädgård. Jag har valt att inrikta mig på markförhållande beroende på klimatet (torr, fuktig och blöt mark) och markförhållande beroende på substratet (sand, lera, humus och torv) samt temperaturbundna växter. Därefter följer en slutsats där jag reflekterar över mitt arbete. ***********This thesis contains a description of plants that thrive and can grow under different conditions in areas with partial or full shade.

Nordisk mytologi : En läroboksstudie

Syftet med studien var att undersöka människors motivation till deltagande inom lagidrott, vilken motivationsreglering som påverkar en idrottare till deltagande inom idrott samt hur uppfattat självbestämmande stöd från tränaren påverkar motivationsreglering, beroende på kön och spelarposition. Undersökningsdeltagarna var 146 idrottare, 59 kvinnor och 87 män, som var medlemmar i olika idrottsföreningar. Insamling av data gjordes i form av personlig kontakt med en enkät som innehöll mätinstrumenten Sport Motivation Scale och Sport Climate Questionnaire. Resultatet visade att det fanns en skillnad mellan könen i yttre reglering. De inre motivations-regleringarna i studien hade positiva korrelationer med yttre motivationsreglering, alltså om den inre motivationen höjs hos en idrottare så blir även den yttre motivationen förhöjd.

Lokal tillväxt - möjligheter och begränsningar i en global värld. Fallet Dals-Ed

When discussing local development attention is often given to the problems involved. Factors like decreasing population and inadequate infrastructure are two examples. Local politics has, however, lately been argued to have possibilities to affect its own development and its chances to achieve growth. Some of the most important factors from this debate are to make a community attractive for people and companies, committed leadership, the local business world with entrepreneurialism and a good business climate. These factors serve as a starting point for this discussion where focus is on the possibilities to achieve growth on the local level and the politics that is used for this purpose.To illustrate the chances to affect local growth I apply the theoretical perspective of regime theory and thereby examine the governing coalitions "power to" govern and not "power over" as the earlier theoretical perspectives in the area.

Förluster i olika ensileringssystem

In Sweden the climate makes it impossible to feed fresh herbage to cattle during many months of the year. During periods when preserved forage must be supplied it is important that this forage is stored in such a way that high quality is retained, both nutritionally and hygienically. Furthermore, it is essential that losses occurring when handling and storing the forage are kept as low as possible. This study compares storage in tower silos, bunker silos, big bags and bales,estimating dry matter losses as well as losses in metabolizable energy and crude protein that occur during storage. The results show that tower silos, bunker silos and big bags, the systems with the largest amount of forage and a long feed out period involve larger losses than bales, which are fed out immediately after being opened. As the feed out rate influences the losses, tower silos and bunker silos should be used during the period of the year when the feed out rate is as high as possible, i.e.

Attraktivare förortskommun : Är interkulturella kompetenser givande varumärkesattribut när mångkulturella förortskommuner vill dra till sig fler företag?

The competition between the Swedish municipalities has increased as the world has become more globalized, which means that they need to become more attractive for sustaining sound finances and not to find themselves to have a downward trend. One possibility to show the attractiveness of a place is by using place marketing and therewith attaining a stronger brand position. There are 20 suburban municipalities in the county of Stockholm, of which six are multicultural or are having a minimum of 20 percent immigrants among the residents. These immigrant areas are segregated based on class, income and culture. Problems associated with these areas have historical aspects that dates further back than modern immigration does.

Projektering av småhus med solvärme som huvudkälla

In this report a study has been done regarding different heating systems on which are the mostcomprehensive with solar heating systems. The report has also been focusing if solar power can beused as a primary heating source for supplying more than 50 % of the buildings total heatingproduction. The University of Dalarna constructed a demo-house for this purpose and according tocalculations the total solar usage is more than 50 %. This house has been made for referenceregarding the design of the heating system of property 5:37.Further studies have been made to compare different heating systems that are compatible with asolar system, where the compared systems purpose is to be independent of direct using electricity. Asystem of this design is regarded as sustainable according to environmental as economic issues.

Säkerhetsklimatet inom Norrbottens läns landsting

Syftet med detta examensarbete var att skapa en lägesbild över säkerhetsklimatet inom Norrbottens läns landsting och ge information om vilka eventuella insatser som skulle behöva genomföras för att skapa ett gott säkerhetsklimat. De frågeställningar som skulle besvaras i anknytning till syftet var: Hur är det allmänna säkerhetsklimatet inom Norrbottens läns landsting? Hur uppfattar de anställda att ledningen förhåller sig till säkerhet inom Norrbottens läns landsting? Hur uppfattar de anställda att den arbetsgrupp de tillhör förhåller sig till säkerhet inom Norrbottens läns landsting? Är det någon skillnad gällande uppfattningen av säkerhetsarbetet inom Norrbottens läns landsting mellan chefer och medarbetare? Studien innefattade en enkätundersökning med 127 anställda och enkätinstrumentet som användes var Nordic Safety Climate Questionnaire (NOSACQ-50). Resultaten indikerar att säkerhetsklimatnivån var relativt hög inom Norrbottens läns landsting. Säkerheten prioriterades av chefer likväl som av medarbetare.

Jämförelse mellan sojaböna och åkerböna som proteinfoder till växande grisar

The soybean can be used in multiple ways, and its high oil content makes it suitable for extraction. Soy bean meal, a by-product of the oil extraction, is a good source of protein with a high feeding value, and is therefore used in a number of different animal feeds. Further, soy bean meal has a low production price, which is one of the reasons for the extensive export of the product. There is a great demand for vegetable-based proteins, especially in the organic production where synthetic amino acids are banned. However, the current production of soy beans is not environmentally sound and that combined with the long transport distances amplifies the need of finding a locally produced protein source.
